Abstract

Dislocation of hemiarthroplasty after hip fracture surgery is a rare complication and mostly occurs as a total luxation of head from acetabulum. In our case, dislocation occured between head of prosthesis and femoral stem after operation with Leinbach type hemiarthroplasty due to intertrochanteric femur fracture . Although head of prosthesis stayed in acetabulum, femoral stem luxated posterosuperiorly. This study aims to emphesize the risk of atypic dislocation in case of incongruency of head and femoral stem of hemiarthroplasty.

Key words: Intertrochanteric fracture, hip fracture, Leinbach prosthesis, hemiarthroplasty
